Great info. Got that problem and will check it out thanks.
All good tips. Another sign to look for is boiling at running temps. If the fluid boils just above normal operation then you have a pressure leak. Fluid under pressure raises the boiling temperature closer to the red mark on the gauge, if it boils against the block then you get air. Air won't cool the block once it starts boiling, so the problem quickly cascades if you notice it happens very fast rather than a gradual overheat, this is likely the issue.. This is caused by a bad radiator cap or broken seal in the system, such as a head gasket or intake manifold gasket. Check the oil and spark plugs for signs of radiator fluid.
Overheating can also induce these failures and may not be the root cause of the original overheating problem. Check the radiator for rust, it may need flushed. Water wetter will thin the surface tension of the coolant, helping it cool the water jackets in the block.
damm good points my friend
Water Wetter?
can this apply to 2014 dodge charger SE 3.6 after replacing the radiator cap, radiator, head gaskets, manifold gaskets also been replaced twice, thermostat been replaced 3 times oddly it keeps going out and yet it there is no air bubbles as well flush it several times that don't help as well unsure why my thermostat keeps going out but once replace it will still over heat. I am stilling having the overheating issues took it to the dealership and other places. Fixed what they said was the problems which is the list above, still can't resolve the issue at hand car stay from overheating if AC or Heater is on once the temp gets to half it will overflow, any suggestions on what maybe my car problem?
Same thing in my kia rio 2009
@@tanishacasel6760im having the same problem… u ended up getting it solved ?
Thank you for all the great tips....I had the exact problem as described and FIXED my overheating issue. It was because dust and debris collected over time which formed a blanket that blocks air flow in between the radiator and the AC condenser.
Plugged up ac condenser is the issue. I worked at dodge and this is a common issue especially in my area because of the fluff from the trees. Just separate the rad and condenser and wash out the condenser with a low pressure hose . It's best practices to do the sane with the rad at the same time . No parts cost just time
What's rad?

Hope you can answer this sir! I did work on a car it ran fine for months then it started to run hot once it got hotter and she ran the ac! I checked a bunch of things replaced things also radiator,temperature sensor, the fans, coolant jug and cap, and thermostat! Now if I spray the condenser with the water hose the temp drop to normal almost instantly! Can this be the reason?
@@clyderobertson8099 Did you find out what it was? And did you replace that condenser? We have same problem w/overheating w/AC on, but only on stops and need to find out what causes it.
When I watch your video I feel you are just talking to me :) Informative videos thank you.

After wrecking my 1995 Nissan pickup I replaced my radiator and various other parts. After getting it out of the body shop the truck started overheating.Went to the mechanic; the mechanic replaced my cooling fan clutch. But it was still running hot but not overheating.So I talked to another mechanic and he checked the coolant in the radiator and found that it was only half full.After adding radiator fluid (prestone)the truck runs great!
Thats great bud. Yes, most cooling systems will benefit from being properly bled of all the air pockets which would allow you to fill it all the way up. Thanks for watching
Thank you Ive done everything Im going to replace radiator
GOD BLESS YOU!!!!! Thank you SO SO MUCH for getting on this for me! In my GUT OF GUTS, I've been continually "thinking" that there's SOMETHING wrong with the radiator....ON THE INSIDE. I brought this to my mechanics attention, but he tried to assure me that I'm getting "proper flow"....I say "BULL SHIT". My car has NEVER run hot...EVER. I know it's getting "old", but I put alot of time and money into this car to keep it running TIP TOP. The very second I hear something that's not right, I go get that checked, and fixed. I never wait until it becomes yet ANOTHER ISSUE caused by the OTHER ISSUE. I was so tempted to just go ahead and purchase a NEW radiator, and get that installed....even it's for "shits and giggles", just to see if that would STOP THIS PROBLEM. Like I had said, as long as I DO NOT turn on the A/C, I'm all good. After I made the mechanic burp the system several times, it's getting a little better now. When I turn on the A/C, it takes a few minutes to for that needle to begin that SLOW climb upwards, but I don't let get too far and go ahead and shut down the a/c, and see if it will go back to "normal" by itself. SOMETIMES, it will....but sometimes, it needs just LITTLE BIT OF HELP by turning on the heater and forcing it back to normal. I have EXTREMELY HOT air that comes through my vents into the car when I do this, but I just put the windows down to deal with it. Once the car is back to normal temp, I cut the heat off and I'm good.
fuckin sad most mechanics are dishonest ppl. always tell you what you want to hear and most of the time they dont fix it they tweak it and keep the money for parts.
Thanks for making the video.
Having the same issue with my 95 accord ordered a new water pump and radiator and keep my fingers crossed. Thanks for your help.

Update?
Etnieus I u
Thanks for the knowledge
You welcome my friend, thanks for watching
If you have a infrared thermometer you can point it at different spots on the radiator too. If you get different temps that will indicate coolant is not circulating evenly
Great point bud
Good information my brother!
thank you for the information 👌👌👌
I have an 07 Mountaineer. I drove it for almost 7 months no over heating... I filled the AC up with freon and the AC started working great. Within 2 days I started having over heating. Only happens when run the AC and only when ac is running and I am going over 40mph if I stay going slow it don't over heat. Being an amateur home mechanic, the best I can figure is either my condenser fan isn't working or my compressor is going out and causing significant drag on the motor causing this. Other than that I'm at a loss. I don't have much experience in AC repair unfortunately.
Im having exactly the same issue
Great info thanks for sharing
Thanks for watching!
You awesome Brother ... 💯 👊🏽👌🏽
Thanks for watching bud, please thumbs up the video and subscribe to the channel, thanks
could it be the AC condenser? my vehicle is also doing this but water pump & radiator are new. it runs below the mid range ' very cool ' until I turn on ac.
Har to find a good mechanic these days ty
My car does fine on the highway but once I stop at a light or while idling my car temperature gauge goes up to the 3/4 mark but goes back down to the middle when I start driving again. The Fans turns on but only when the AC or Heater is on. What could this be? I bought the car off someone so I don't know what's been done to it.
This is my exact problem, I changed my thermostat and it still happens I think it’s a problem with the radiator
@@rdb6677 Same happening to my 370z i wanna say its my radiator because my car cools down when i have the heater going inside so maybe my radiator isnt doing enough?? Do you have any updates with yours?
.
Tengo el mismo problema en un accord 99. Tienes algún update al problema?
Did you ever figure out the problem
I just replaced the Radiator in my 08 PT myself. Was leaking where the alluminum met the plastic on top. Bought a new readiator, hoses, and clamps, lifted the car up on one of them drive up stands or whatever they're called and disassembled the whole front. I'm not mechanically inclined so it took me 4 hours to change it all but finally got it done. Filled it up, Bleed the system, let run to temp, had a OBD on it to monitor temps, once it reached 100c, I shut it off. Heard some boiling and went out and bought a new thermostat. One that opens up at 180F instead of 195f. Which is all Autozone had in stock. Lo and behold, everything is normal again.
When I first got it all together, I suspected my water pump because the top hose was warm but the bottom was cold. (But I had heat) But, it was the thermostat stuck closed. Probably from sitting for 6 months during winter. Thankfully the water pump was not the issue. Where the job is tedious and annoying and mildly frustrating, it was easy enough to do yourself. Few RUclips videos on how to do it too which is what i followed. Saved me $250-$350 in labor. Happy to have done that.
Now, with the radiator done, new Coil Pack, Plug Wires and NGK spark plugs, my PT is now ready to be sold to a new owner. Sadly selling one of my 2 PT's to get a Ford Escape. But, for anyone who needs a new radiator, save some money, devote a few hours and change it yourself. Bleed the system through the bleed valve or you can purge/burp the system using a radiator burp kit you can find online or in-store if its in stock. Worth the time and hassle to save $250+. In my opinion at least it is worth it.
Good job my man, it doesnt matter how long it took you, you managed to save some money doing it yourself. Thats whats up
You also feel good about yourself afterwards. Had it today for a good 50 mile run. Watched the fluid levels in the resovoir abd didnt budge. So system is fully purged now. No leaks. And my temp guage stay well below halfway thanks to the180f thermostat. Now I just have to reset 3 sensors and she will be ready to sell.
In all ur 3 videos u never mention replacement of temperature senser which sits to side of the thermostat in a little screw in senser u need to first find it its hidden pull clip back then un screw senser . That is another way . If ur # 50 fuse is good and relay is good and thermostat good radiator cap good. Chance sencer reading not good water coolant not reaching levels it supposed to be . And it over heats .. please talk more abought this senser includes in ur video and yes im a avid subscriber best channel out here i only go off urs .. thank u marlon in lasvegas #1fan
I have a suzuki swift center antenna...temperature gauge goes up occassionally..
I did,
Cleaned radiator
Blockage cleaned in thermostat and removed it
Checked fan and relays
Replaced head gasket,fixed a leakage in water jackets..
Currently water level remains same..still temperature indicator goes up especially while idling with ac on..when i switch it off,it comes to normal level...
Water fan,pump was also checked and in order...
Thanks ice cube

Lmao...thanks for watching please remember to thumbs up the video and subscribe to the channel..thanks
Lol. Where you get the blunt impression from?
I replaced thermostat water pump clutch fan it over heats when I’m going 90mph in a 2006 Colorado or when stopped in traffic heater works great. Water boiling at the radiator but not in the reservoir
I went back and listened really close to this video again. You said in one point, that it COULD BE a warped head by it overheating BAD....but It's NEVER gone to that level. I've never allowed it to. The moment I see it getting about 2 needles width above the normal, I shut down the a/c...and turn on the heater. The only time it was 3/4 of the way up was that one time, a few weeks ago, but it still was not into the HOT ZONE yet....thank God! LOL
Well knowing that is assuring but it really doesnt take much to warp an aluminum cyl head..But if your radiator not partially clogged or allowing coolant to properly flow like it should, then that combustion test should be perform.. Get your radiator checked/replaced and go from there..But from all my years of working on these cars concerning overheating, all the very last repairs that was done ended up with a cyl head,..Hope thats not your problem but it very well could be..Good luck buddy
Thanks so much! I'm praying that it's only the radiator...and not the bigger of the evils. Like I said...I have no milkiness in my oil and no white smoke either...so I'm hoping it's the radiator.
I'm having the same problem. 1st overheat today, with none prior, so overheating should not have caused the warped cylinder head prior to today. If pump, thermo, and fan are working, it must be the radiator I guess. It's confusing though, because: if it's a partially clogged radiator, why does it only happen with the a/c on?
Liked, subscribed, and a member of E's notification coalition 8^D
EDIT: going to get the codes and make sure my low speed isn't out on the fan. I'm 99% sure I had no overheating g before today, and my test drive just confirmed absolutely no heat problem with a/c off. So to repeat myself I guess, why does it only happen with the air on? So weird. But I got this car in good shape with 60K on a '06, for a G! One single G! Could have bargained but it was family. Still, worth fixing and getting all I can out of her.
An 06 PT with 60k not bad at all..Buddy that low speed fan should kick on no later than at least 20 seconds after the compressor kick on..But you doing right to get fan checked cause this will def cause your problem..Unless your compressor pulling an excessive amount of current from your engine causing it to overheat, your problem most likely caused by the cooling sys such as a radiator flow problem.

I have a infinity M45 Sport 2008. Over heats when a/C is on over over 95 degrees hot out side have been check fans and water pump temperatures in motor everything running normal what can it be ??
I don’t have a radiator water bottle. All I have as an expansion/overflow bottle connected to the hose just below the radiator cap. How do I gauge the amount of fluid to put into the radiator?
Our 2003 Chevy Cavalier (~111K) overheats only when AC is on and on stops. But the car has another problem w/knocking sound when it starts to move. The frequency depends on rpm, and it doesn't change if to switch gears. No sound (knocking noise) on idling. The sound is heard in the area of engine, looks like more on the right side. Can those 2 problems be related? Thank you for this informative film.
2003 jaguar x type fans work intake gaskets new new radiator new water pump fans work no leaks I took the thermostat out cause they were sticking put blue devil in it and it still running hot
i have a 2002 1.8L Nissan Sentra that overheats with the AC on. without the AC on the temp gauge for the coolant is slightly under the halfway mark, I pulled a vacuum on the AC system for 30 min+. Filled the system with refrigerant using a scale. The compressor clutch never seems to cycle...should it? stays on watched the clutch for over 20 min. shortly after turning on the AC the temp will spike. will spike too on the freeway going 70mph at that speed probably the fans have little to do with the cooling?, not sure first car ever had with overheating issues. I bought the car cheap had a blown head gasket, probably what is wrong with this caused that. I put on a new head gasket , runs great....except for the AC issue, air ice cold with the AC on, will try what you suggested. any other suggestions....thanks for taking the time from your busy day to create the video
Some what true i had the radiator clogged in my van so i can confirm that what this guy says is true in some cases.
Ye it's not always the same case for you ya know
The AC runs the Fan assembly at HIGH RPM (by Fan Relay #2) to draw airflow through the condenser and the radiator, simultaneously. The Fan has 1 motor & 3 wires. Low input, High input and Ground. Lots of times, the High input fails. Cars like this have ZERO airflow below 35 miles per hour. Use scan tool, repeatedly turn on low and then High Fan with Scan tool under "Output / Relay Tests". If you activate the High Fan relay and NOTHING HAPPENS... Replace Fan assembly and BOTH RELAYS. There is a BIG issue with 1 fan vehicles doing this exact same issue. Overheats at low speeds/ Idle, with AC on. Hope this helps. There is a TSB on this exact same issue, too. GM, Chrysler, Ford, Honda, Infinity, Toyota...ETC... You name it. 👍😎
@jasonpocaro2730 Thank you. i think that what it is w/our 2003 Chevy Cavalier (~111K). It overheats only when AC is on and on stops. But the car has another problem w/knocking sound when it starts to move. The frequency depends on rpm, and it doesn't change if to switch gears. No sound (knocking noise) on idling.

@@olenaerhardt7725 Difficult to say for sure. You need an inspection. Could be engine related but not 100% sure. Find someone who you trust to look at it and give an estimate for repairs.
@@jasonpocaro2730 I didn't find such a mechanic yet. As DIY mechanic I try to do everything I can myself, but of course there are some complicated projects you need a good professional. In such cases I usually go to a dealer to surrender. Hopefully that knocking is not Connecting Rods. Thank you for your opinion.
Engine overheating with A/C on could also be a clogged A/C condenser or failing A/C compressor too. The failing AC system could be putting strain on the engine since the A/C system and engine cooling system are directly related to each other..
Also if you have 2 cooling system fans,both should be working.

So if I have no eat and new oem thermostat was put in still over hears
That means water pump?
I found that one hose is hot and the other isn't hot. The ford escape doesn't show overheating on dash and is in the middle. I turn heat on and works. The ac has high psi presure maxed and low pressure is at 30 psi. So the compressor turns on and off here and there. When hot days ac cant feel cold. Lower temps yes. And then i have the fans always going on high speed even when start up the next morning . Right after 1 min is runs on and is barley off. Mostly more on all the time than off. Mecchanics still keep saying we cant find anything. Engine light goes on and off and at the mechanics always seems to be off . Trying ro gwt them to scan the system. Maybe because im in a small town, but not many options here. Any suggestions would be much appreciated. My coolant is at perfect level as well. Its a 2010 ford escape XLT 3.0L V6
I leftmost ac on with the engine being on fore about 4 hours and now my engine light come on what's wrong with it does it need to cool off or did it drain energy

Here is my story,2 summers ago my 1998 honda accord 150,000 miles on it a/c will stop cooling followed by slight overheating in3/4 mark close to the red.I replaced both cooling fans,still the same,I replace the radiator,still the same,I replaced the rad. cap,still the same.I replaced the temp.sensor it still the same, I replaced the thermostat just today.
I got a fan that doesn’t work in my wife’s honda. One fan works the other doesn’t. It’s freezing cold out so I don’t think the fan would be causing it to overheat?
I replaced the thermostat with no luck. It’s only when the ac/heat on and it will bog out like it’s pulling to much power and then starts overheating…. Any idea???
Guess I’ll be checking my hoses today.
But something tells me it’s the head gasket even tho I have no other signs of it.

Hey I have a 2004 accord. Everything works fine. When I'm idle at a red light or if I park the car and keep it on (while a/c is on) it begins to overheat.. only thing that has been replaced is the alternator and a/c pump. Also only one fan comes on when the a/c is on. The one on the right doesn't come on. Could that be the problem?
yes, that very well could be your problem. If you have a dual fan setup blowing thru the condensor, both fans need to be operation in order to work properly...Please subscribe to the channel, thanks

My friend you give few tips to what cause the over heating, but you forgot to mention the fan clutch, if is bad the car going to be. over heating when you turn the a/c
Yes, a fan clutch can def cause that. Most car makers have gone from using fan clutch setups and this car was not equipped with one. But you right, it can cause that

I've got 2002 PT cruiser and I just replaced radiator and thermostat and it was fine for couple days then it overheated...any suggestions?
Yes, suggestion is to start the diagnosis properly. Im not gonna just throw a part at you and advise that you replace it because diagnosis hasnt been done. Now, from the top, start with the simple approach. Is the cooling system properly filled meaning free of any air pockets? (was it bled) From there move on to the next stage, are your cooling fans running? you see where im going with this? guessing is a waste of money.

Thanks for watching and subscribing my friend. Listen, you gonna need a better way to verify if your car overheating.. Most cooling fans do not even come on until after maybe 220 degrees. Why do you thinks its over heating? is the temp gauge in the red? Check and do the small things first such as verify the sys is full with know leaks

Will my silverado 5.3 overheats but when I turn on the heater it normalize what can it be
Probably your radiator is stopped up. You need a new one or flush.
bro i have a 01 silverado n it overheat to 230 when the ac is on once i turn off the ac n drive normalizes only on hot days it does it thou n wont happen no more
What should I do
make sure the a/c compressor is working properly if not, might be putting extra load on the engine when is working causing overheating.

Hei.I have everything working fine, but when the car heats up to 90 degrees, the air conditioner turns off and does not work, and every time I turn it on it turns off, why?
Greetings to you
Of you have time, of like to ask you a quick question please. Will the check engine light come on when overheating?
There are sensors on most cars that monitors coolant temp. So yes, its possible a CEL can come on for that. Are there any codes? Also are you subscribed to the channel?
@@OnlineMechanicTips Yes, I'm subbed. I'm going to try and check codes in the morning. My wife just told me the heater was intermittently blowing cold in the Winter. I'm leaning towards thermostat but I'll check the hoses, fans...ect in the AM. Thanks friend 👍
Im having the same issue with a 2012 town an country 3.6.
It runs fine till i turn on the ac an it gets hot quick.
My 2012 crv with 415k has the problem. The temperature guage goes up after turning the ac on for a while then turn the heater on and the temperature guage goes down. So I changed the thermostat but the problem still there. Then today I changed water pump which was making growling noise.Then I took out the radiator spray cleaned it and spray cleaned the AC condenser grill. Put everything back together drove around it
Everything was perfect for 20 minutes then temperature guage started going up again. Tomorrow I am going to change the coolant temperature sensor. If It doesn't fix the problem then buying a new radiator. Wish me luck guys. Changing the water pump on a 2012 crv is pain in the rear.
did that fix it or did you get a new rad?
Can you answer some of my questions?
I got a 1999 Ford Crown Victoria Police Interceptor and the car overheats when the AC is on it'll run all day long here in the 112 degree heat in the desert if the AC is off. Replaced the compressor, condenser, accumulator, orifice plug, and radiator cooling fan. Also replaced the relays and fuses, and have a brand new radiator as well. And after all of that the damned thing still overheats when the AC is on, the compressor clutch kicks on and off and the brand new radiator fan doesn't come on I'm at my wits end, got the replacement cable for both the fan and the compressor and gonna use my guages to check refigerant levels. Any suggestions?

Hey my friend, its hard to say. You left out what year the car is but im pretty sure the fan is monitored by the computer..Which means you will need to get inside the computer first to at least see if theres any faults...There could be some fan related fault codes inside the computer..I suggest starting there.

My car is over heating I changed the radiator and the lower and top hoses. But now its still overheating and leaking from a hose that behind the engine. What could it be. I have a acura mdx 2002
Hello my friend, without actually looking at it ide suggest you get the leaks fixed before getting any other parts replaced. Best somebody use a coolant pressure tester to pressurise the sys in order to find and fix all the leaks. Then get the cooling sys properly bled of all air pockets then test drive to verify.

I have a 2009 Chevy equinox in when I turn my car off fan come on I change thermostatic in it stay on any suggestions
ECT switch
It's the defect thermostat, take the thermostat out and leave the the A/C on high
check condenser fins and change it
This would be the case if this ya problem. Its hard to advise somebody to check the fan and change it..what if ya check reveal nothing?
hi, i got the same problem, when i go uphill with ac on, my temp gauge keep raising, when ac off its normal temp, what i change from my car, radiator, radiator hose, thermostat, fan switch, temp sensor, radiator fan and ac fan, and water pump, head gasket on my car is in good condition, what else wrong with my car,
Curious, how are you so sure your head gaskets are in goo condition? Also are you subscribed to the channel?
I did as told ... when the truck was overheating while ac on I switch to heater and the air was cold 😓... so is it the water pump?
This could be the case ONLY if the cooling sys full and free of any air pockets. So if this the case then yes, your water pump not doing its job..Thanks for watching, please thumbs up the video and subscribe to the channel, thanks
I have a Toyota rav 4 2004 and my car over heats when I put ac on. I put in a new thermostats, radiator, catalyst converter, and a new oxygen sensor on both top and bottom. What could this be. Please help I’m at my wits end. New subscribers here.
How did you fix it pls ?
2013 caravan runs hot when idle with ac on temp normal when on highway
My truck keeps heating is in the middle of the middle and the H and it has coolent and a new water pump and on white smoke
My charger 2007 was overheating a quickly pulled over, I turned off the ac and started to cool down, I waited and started to look at RUclips video and the car trun off and now I can get it to start what could be my problem
Did you find out what the problem was
If it overheats turn on the heater but you have to turn it onto the vents the ones that blow on your face or it won't cool off your car the defrost are selection doesn't work
Explain
@@OnlineMechanicTips when you don't have any other way to cool off your motor as a last resort and turn on your car heater... But in my car I have to use a selector switch to put it on vent the one that blows on your face if I put it on the one that blows underneath the windshield it doesn't cool off my motor very well. My cooling fans don't turn on often enough if my car is sitting at a drive-thru window.
then why don't they put the radiator n front then?
A/C works, cold air, but when I put max AC i hear a very noticeable grinding?!! noise coming from the passenger side (imagine how loud it is that you can hear it with max ac on). After literally 20-30 seconds the Temp gauge was at 3/4 (almost to boiling hot). I was on my phone in a parking lot and thank god I saw it. I have NEVER seen my temp gauge that high before, and I would like to know what my problem is. The car in its 10 years of ownership has NEVER reached temps above the middle.

Did you find out ?
Nino Bino Yes. I have some air in my coolant system which I have to let out once in 2 weeks. Also my AC bearing is shot so thats why it makes that sound. AC condenser, water pump and radiator all working perfectly. There’s just a leak somewhere
Could be air in the system
You exacly right
Car overheats at idle but it's fine on the highway. What is it?
Hello bud, keep in mind, there is no cooling fan needed on the highway but its very much needed at idle. You might wanna look into that electric cooling fan. Please subscribe to the channel, thanks
The new thermostat won't open on time that's why it's still overheats ,the psi is too high
So my buddy’s car says it’s over heating and it says to turn the a/c off. When you turn the a/c off the temp almost instantly goes down to normal. What could this be
Mine does this as well and everything has been replaced.
Did you guys figure it out?
@@mygoodnessmate I have a 2000 Jeep Grand Cherokee and the mine was the fan relay switch behind the passenger head light. The wiring harnesses was bad so I replaced it and the relay and my problem was solved.
Hey man. My car overheats when I turn my AC on and the AC system make sounds. Could that be the radiator fan motor problem? Thank you.
Very well could be my friend.. Simply look down in the area when you hear the noise, if you see the fan blade slapping on anything or making noise, may be time to get it replaced. Thanks for watching, please subscribe to the channel for me, thanks
@@OnlineMechanicTips thank you for the tips!

ac compressor is probably going bad, it’s probably putting more load to the engine causing overheating.
@@jdlr72 thanks for the info, that also might cause this problem. But in my case it was the radiator fan, I got it replaced and it solved the issue.
Check your AC compressor probably its high pressure or not working properly it can cause also overheating during usage of airconditioning due to high compression of the AC compressor
With Heater on my engine area gets hotter!!! Much hotter!!! I'm trying to find out why its overheating period!!! In other words the heater on doesnt help it,it makes it worse.....and heater works fine.
i have ford flex,it heats up when i turn a/c on.what can be the problem?
Hey did u get the solution
Did you find out what it was? Mine does that too.
I already replaced new cooling fan but it is not working either .but we tested cooling fan before installing it.it was working.And a/c working either.Mechanics cannot figure out what the problem is either.
What if I have replaced thermostat and water pump and radiator 😫
If you 100% sure the sys is properly bled free of air then its now time for a block test..This test will reveal if you getting exhaust gases into the cooling sys..By way of maybe a head gasket or warped cyl head or even a block..You have to get this verified before assuming the worst like this..Please subscribe to the channel for me, thanks
I have a Chevy transverse 2013 my truck says hot engine Idle hot
